The Stenka class is the NATO reporting name for a class of patrol boats built for the Soviet Navy and Soviet Allies. The Soviet designation was Project 205P Tarantul (not to be confused with the Tarantul class corvette). The boats are an anti-submarine patrol boat version of the Osa class missile boat

Design

Project 205P Stenka is a variant of the Project 205 Osa missile boat. The Stenka used the hull of the Osa class and had a slightly larger crew. The development office of the "Alma" Shipyard in Leningrad used the standardized components of the Osa missile fast patrol boat, in order to develop an anti submarine boat. The anti ship missile launch containers were replaced by four torpedo tubes but the anti-ship missile related structures and equipment were retained. The living spaces in the Stenka were improved for long patrol endurance by raising the superstructure in order to create more usable space inside, compared to the Project 205 Osa missile boat. They also installed a more powerful air conditioner.^[1]

The drive system is three diesel radial engines of the type M504 B2 with a total capacity of 15,000 hp.

Armament

The primary ASW weapon for combating submarines were SET-40 torpedoes. The boats has four 406-mm torpedo tubes installed on the deck in the aft part of the boats, two on the port side and two on starboard side.

Behind the torpedo tubes on the aft deck, in the port and starboard sides, are each one Abrollgestell depth charge launcher. Twelve depth charges, six for each launcher can be carried.

As the boats of the Project 205 Osa class, the Project 205P Stenka boats has two radar-controlled AK-230 30-mm twin guns, one in the bow, the other at the rear.

One of the boats was tested with a 57-mm gun AK-725 on the bow and received a modified project number - 205PE.^[2]

Sensors

To search for air and surface contacts with a 205P project is MR-102 - (NATO: "Pot Drum") or a "positive" - Radar (NATO: "Peel Cone") provided that are installed on the mast. Including two antennas on the mast of the system to be friend or foe identification attached, which NATO described as "High Pole B".

For directing the fire of two guns AK-230-Towers is a fire control radar of the type MR-104, which was christened by NATO 'Drum Tilt ", mounted on the rear of the building.

The search for submarines, the ships with an MG-345 "Bronza" system fitted, which consists of a submersible sonar -type MG-329 "Sheksna" as well as the corvettes of Project 133.1 bear, and a MG-11-"Tamir-11" sonar sensor composed of the fuselage.

Ships

Soviet Navy

A total of 114 or 117 (sources vary) boats were built between 1967 and 1990. They were operated by the Maritime Border Guard

The Soviet Union classified the boats of their border troops as "border guard ships" (Russian Пограничные сторожевые корабли (ПСКР)) and the five boats of the Navy as a gunboat (Russian артиллерийский катер).^[3] A similar allocation of boats for submarine control are designed into the regular border security, which in the NATO countries is rather unusual, so that project there as 205P patrol boat is kept.

• Russian Navy - About 19 survivors are operated by the Russian Coast Guard
• Azerbaijan Navy - 5 boats
• Ukrainian Navy - 10? boats (may be operated by the Ukrainian Sea Guard)
• Georgian Navy - 2 boats (1 - "Batumi" was scrapped in 2006, another - Giorgi Toreli sunk in the Battle off the coast of Abkhazia)

Export

• Cuban Navy - 4 boats exported in 1985
• Cambodia - 5 boats transferred 1985-87
